Application october K16, I1956-, serial No. misgaat 2 claims. (c1. 9s-s1) This invention relates to a 'building and air distributing structure and more particularly 'to a building and air conditioning structure 'of the type forming the subject matter of United States patent to R. P. Goemann, No. 2,729,429, dated January 3, 1956.

The Goemann patent discloses a building and air conditioning and distributing system and apparatus wherein cellular metal oors form the load supporting structure at each of selected stories of a multi-story building, and the present invention has for an object to provide novel apparatus for conducting air from one or more of the air conducting floor cells.

A further object of the invention is to provide a novel, simple and economical ceiling outlet structure for discharging air from an air conditioning cell of the multicellular floor illustrated in the Goemann patent above referred to.

A still further object of the invention is to provide a novel and highly useful elbow shaped duct unit which may be economically manufactured and used with advantage in suspending a ceiling outlet from the underside of the multicellular metal floor illustrated in said Goemann patent.

With these general objects in view and such others as may hereinafter appear, the invention consists in the duct structure, in the ceiling outlet structure and novel elbow duct unit Ahereinafter described and particularly defined in the claims at the end of this specication.

In the drawings illustrating the preferred embodiment of the invention:

Fig. 1 is a diagrammatic plan of a portion of a cellular metal oor wherein air is conducted through selected floor cells as shown in said Goemann patent above referred to;

Fig. 2 is a cross sectional view on the line 2- 2 of Fig. 1 viewed in the direction of the arrows;

Figs. 3, 4 and 5 are views respectively in perspective, end and side elevation of the elbow shaped duct unit forming a component of the present ceiling outlet structure;

Fig. 6 is a vertical sectional detail illustrating theembodiment of the elbow shaped duct unit in another duct structure to be referred to; and

Figs. 7 and 8 are views in plan and end elevation of the elbow unit shown in Fig. 6.

In general the invention relates to a ceiling outlet structure and also to an elbow shaped unit forming a component thereof. The ceiling outlet structure is designed to enable air to be distributed therethrough from air conducting cell 10 forming a part of the flooring and air distributing structure shown 4in the Goemann Patent No. 2,729,429. As herein shown, 12 designates the elbow shaped connecting duct which is preferably designed for cooperation with an adapter fitting 14 arranged to be clamped about an opening in the lower wall of the air conducting cell 10. The adapter ring 14, herein shown, comprises a cylindrical ring 13 having upper and lower flanges 15, 17. The interior wall of the ring is provided Ilit'tsbil'r'gll, P51., -acorporation of 2,908,21 1 `Patented oct 11959 with integral lugs 11. lA clamping 21 zhaving a flange 23 is arranged Yto be'clamped with the flange `2?, engaging 'the finter-ior surface of fthe portion of the'du'ct surrounding the 'opening therein and through which the air discharges into the outletA from th'efair carrying .conduit 10. The clamping `ring 23 is also provided with 'an .inner flange .25, and `-suultable lbolts serve 'to clamp the ila-nge oft-he clamping rin-g and the upper iiange 15 of the. ring 1 3 `in operative land airtight position on `the underside of the 4air carrying 'duct1\0. Apsuitable gasket `27 is provided between the -ange I15! and 4.the under-surface of the duct "1'0 to maintain anairtight joint. The inlet end of the elbow shaped A.duct ,12 is bolted to the lower ll 'f e 1'7 of 4the `adapter ringin the manner illustrated in Fig.l l2. Y i g n As yilll`1st`rated,the elbow shaped connecting' duct 12 comprises 'a hollow curved member having a ange 20 at one end for cooperation ywith the lower flange of the adapter 14. A gasket 22 may be inserted between the flanges, and the anges may then be tightly secured together by bolts 24. The other end of the connecting duct is provided with a flange 26 disposed in a plane at right angles to the plane of the ange 20 and is connected to the flange of a stack member 16 by bolts 28 with a gasket 30 inserted between the flanges to assure an airtight seal.

The second flanged end of the stack member 16 may be secured to the linet of a ceiling outlet box 18 of any usual or preferred structure having an outlet opening in one wall thereof. The stack member 16 may be constructed of two symmetrical half sections and may be provided with one or more control dampers 19. As indicated in Figs. 3 and 4, the connecting duct 12 is preferably made in two symmetrical half portions having flange seams which may be provided with a cementitious compound and then spot welded together to form an airtight structure.

As illustrating the utility of the present elbow shaped duct unit I have illustrated in Fig. 6 the details of a structure wherein provision is made for conducting air from one of the air conducting cells 10 through an opening in the underside thereof and at a point laterally spaced from a discharge outlet (not shown) mounted on a stack member 41 to dispose the outlet on the upper side of the cellular metal lioor above referred to. As herein shown, the stack 41 is bolted to a flanged adapter 43 and the latter secured to the upper flange of a duct section 4S extending through an opening formed in one of the cells of the iloor and to which an adapter 48 is bolted as shown. The adapter 48 is provided with a lower flange 49 to which the upper flange 42 of the elbow shaped duct unit may be bolted as shown at 36. A suitable gasket 51 is provided to insure a tight joint, and a second flanged end of the elbow unit 44 may be bolted to the flanged end of a duct section 52 extending under the ooring and connected at a laterally spaced point to the opening in the air carrying cell.

From the description thus far it will be observed that the components of the ceiling outlet structure including the elbow duct unit, the stack member and the outlet box itself may be manufactured in the plant, and the erection of such units may take place in the field involving minimum erection expense. By the provision of connecting stack members 16 of varying lengths it is possible to dispose the outlet at varying points under the lloor. The present ceiling outlet structure, therefore, enables the manufacture of these parts to be standardized and at the same time offers reasonable variations in the disposition of the outlet during the erection in the eld.

While the preferred embodiment of the invention has been illustrated and described, it will be understood that the invention may be embodied in other forms withinthe scopel of the following claims.

, 3 Y Having thus described the invention,lwhat is claimed is: Vl. The combination withamulticellular floor having an air conducting cell `provided with a longitudinally extended opening in the bottom wall thereof, of a ceiling outlet structure (through which air may be discharged,' said ceiling outlet lstructure including a hollow'felbowy shaped duct Vhaving substantially rectangular'opening's at the inlet and outlet ends Vthereof andprovided with outwardly extended flanges at said ends lying-in planes dis posed at right angles to each other, the long dimension of the outlet being disposed transversely of the long dimension of the inlet, said inlet extending longitudinally of the cell, means ,for suspending the elbowduct from the underside of the cell and in clamped relation-about said opening including a anged extension secured in airtight relation to the duct and to said-inlet llange, said outlet structure further including an outletbox, and a flanged conduit interposed between and secured in airtight relation to the outlet box and to the outlet ilange of the elbofw duct, the longitudinal extension of the inlet 'occupying a minimum of width of the air conducting cell to retain the structural integrity of the floor, and the transverse extension of the outlet permitting a relatively short overall height of the elbow duct unit to occupy a minimum of ceiling space.Y 1 Y 2; A ceiling outlet structure as den'ed 'in claimV l wherein the elbow-shaped duct is fabricated in two symmetrical half sections having outwardly extended seam flanges along theirfconnecting edges and welded together in airtight relation. ,t
